Ti-Line 清酒威士忌杯

The double wall really does its job—my warm sake stayed steaming for a solid twenty minutes while I sat by the fire. It's tiny but feels surprisingly sturdy in the hand, and the lack of any heat on the outside is a nice touch.

Dropped this into my pack for a weekend campout and the double wall really does its job—poured warm sake, left it sitting for twenty minutes, and it was still pleasantly hot to sip. The shot-glass size is perfect for a quick nightcap by the fire, and the titanium feels featherlight yet sturdy.

Held a cup of hot sake through a whole chilly evening by the fire and the outside never got more than slightly warm—the double wall is genuinely effective. The titanium feels featherlight in the hand, too, which makes it perfect for packing on a trail.
